How to build spy gear
Impress your little gumshoe when you discover how to make spy gear for kids.

Kids love spy gear. Spy gear is easy to build if you have some instructions. Sometimes what's made at home turns out to be even better than what's sold in the stores. These spy gear projects also make for great quality time between you and your little secret agents. The kids will love creating their very own materials, and will also enjoy testing their spy gear with their friends. They will be able to lift fingerprints just like on television, write secret letters with invisible ink they make themselves, and spy on their friends with their newly built visual spy gear. So grab your kids and let's build spy gear!

Instructions

  1. 1

    Create fingerprint dusting powder with cornstarch and soot mixed together in equal parts. Soot from a candle, or fireplace, or grill can be collected by a parent and mixed with the cornstarch. It is then dusted over suspected fingerprints, and brushed away with the paintbrush. Any apparent prints will remain. Use a piece of clear packing tape to lift the print.

  2. 2

    Pour some lemon juice into a cup. Dip your marker into the lemon juice and write your secret spy note. The writing on the paper will appear to be invisible, but when you hold it up to a light bulb, it magically appears.

  3. 3

    Make a spy glass to see what is going on in the room while hiding behind the sofa. Place a crystal clear marble inside a rolled up piece of dark paper. Roll the paper tight enough so that the marble can slip to one end of the tube without falling out. Secure the tube with tape. Peek out a bit from behind the couch, peer through the spy glass, and see what sneaky characters are coming into the room. They won't see you, but you will see them.

  4. 4

    Wrap a plastic cup with aluminium foil. Place the cup against the wall (open end facing the wall), with your ear against the narrower end. This age old trick makes for great spy gear! The cup will enhance the sound in the adjoining room, so you can do your spy work.

Tips and warnings

  • Be careful to collect soot that you are sure has already cooled, and should only be done by an adult.
  • When reading invisible ink, be sure not to put your paper too close to the light bulb, or it can burn.
